Titanium is a transition metal, one of the elements found in Rows 4, 5, and 6 of the periodic table. It has an atomic number of 22, an atomic mass of 47.88, and a chemical symbol of Ti.

Properties

Titanium exists in two allotropic forms, one of which is a dark gray, shiny metal. The other allotrope is a dark gray amorphous powder. The metal has a melting point of 3,051°F (1,677°C), a boiling point of 5,931°F (3,277°C), and a density of 4.6 grams per cubic centimeter. At room temperature, titanium tends to be brittle, although it becomes malleable and ductile at higher temperatures. Chemically, titanium is relatively inactive. At moderate temperatures, it resists attack by oxygen, most acids, chlorine, and other corrosive agents.
